Security Summary

CVE-2025-26549 is a Cross-Site Request Forgery (CSRF) vulnerability in the WP Html Page Sitemap WordPress plugin (wp-html-page-sitemap), affecting all versions from n/a through 2.2. Published on 2025-02-13, the flaw enables Stored Cross-Site Scripting (XSS) and carries a CVSS v3.1 base score of 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), mapped to CWE-352.

Unauthenticated attackers (PR:N) can exploit this over the network (AV:N) with low complexity (AC:L) by tricking victims into user interaction (UI:R), such as visiting a malicious site. The CSRF request injects malicious payloads into the sitemap, resulting in stored XSS with changed scope (S:C) and low impacts on confidentiality, integrity, and availability (C:L/I:L/A:L).
